Tievebulliagh
Tievebulliagh () is a mountain in the Glens of Antrim, Northern Ireland. It forms part of the watershed between Glenaan to the north and Glenballyemon to the south. It is situated about 4.4 km from Cushendall. Geology Tievebulliagh is formed from a volcanic plug, the intense heat generated by molten basalt has given rise to the formation of a durable flint, porcellanite, which is found at the foot of the eastern scree slope of the mountain. Three small outcrops of porcellanite can be seen on the higher south-east slope. Archaeology Evidence has been discovered of a Neolithic axe quarry at the foot of Tievebulliagh. Flint axe heads fashioned from porcellanite that originate from this quarry have been found across the British Isles, from the Outer Hebrides to the south coast of England and across the rest of Ireland. The site compares with the Langdale axe industry based in the English Lake District and the quarries at Penmaenmawr in North Wales, where large num ...

Porcellanite
Porcellanite or ''porcelanite'', is a hard, dense Rock (geology), rock somewhat similar in appearance to unglazed porcelain. It is often an impure variety of chert containing clay and calcareous matter. Porcellanite has been found, for example, in Northern Ireland, Poland and the Czech Republic. Tievebulliagh At Tievebulliagh, Northern Ireland, porcellanite is a tough contact metamorphism, contact metamorphosed hornfels formed from a lateritic soil horizon within a basaltic intrusive/extrusive sequence. The rock is black to dark grey in colour. Tievebulliagh is the site of a Neolithic axe or stone tool quarry, and there is another quarry on Rathlin Island. It is likely that roughouts or roughly-shaped prehistoric tools (Celt (tool), celts) were chipped on site before transportation both within Ireland and over the Irish Sea to Britain. It is also likely that the final polish would have been performed near the site of use in cutting vegetation and trees. It was commonly polished ...

Langdale Axe Industry
The Langdale axe industry (or factory) is the name given by archaeologists to a Neolithic centre of specialised stone tool production in the Great Langdale area of the English Lake District. (For accompanying material seSupplement 1of same volume). The existence of the site, which dates from around 4,000–3,500 BC, was suggested by chance discoveries in the 1930s. More systematic investigations were undertaken by Clare Fell and others in the 1940s and 1950s, since when several field surveys of varying scope have been carried out. Typical finds include reject axes, rough-outs and blades created by knapping large lumps of the rock found in the scree or perhaps by simple quarrying or opencast mining. Hammerstones have also been found in the scree and other lithic debitage from the industry such as blades and flakes. The area has outcrops of fine-grained greenstone or hornstone suitable for making polished stone axes. Such axes have been found distributed across Great ...

Rathlin Island
Rathlin Island ( ga, Reachlainn, ; Local Irish dialect: ''Reachraidh'', ; Scots: ''Racherie'') is an island and civil parish off the coast of County Antrim (of which it is part) in Northern Ireland. It is Northern Ireland's northernmost point. Geography Rathlin is the only inhabited offshore island of Northern Ireland, with a steadily growing population of approximately 150 people, and is the most northerly inhabited island off the coast of the island of Ireland. The reverse-L-shaped Rathlin Island is from east to west, and from north to south. The highest point on the island is Slieveard, above sea level. Rathlin is from the Mull of Kintyre, the southern tip of Scotland's Kintyre peninsula. It is part of the Causeway Coast and Glens council area, and is represented by the Rathlin Development & Community Association.

Penmaenmawr
Penmaenmawr (, ) is a town and community in Conwy County Borough, Wales, which was formerly in the parish of Dwygyfylchi and the traditional county of Caernarfonshire. It is on the North Wales coast between Conwy and Llanfairfechan and was an important quarrying town, though quarrying is no longer a major employer. The population of the community was 4,353 in 2011, including Dwygyfylchi and Capelulo. The town itself having a population of 2,868 (2011). It was named after Penmaenmawr mountain, which stands above the sea immediately west of the town. Much of its formerly rounded top (with an old hill-fort) has been quarried away, leaving the present-day lower flat top. The town was bypassed by the A55 Expressway in the 1980s, losing its old Edwardian period promenade in the process, which was largely replaced by a modern one. Penmaenmawr is noted for its spectacular mountain and coastal walks. Nearby are the popular attractions of Bwlch Sychnant (Sychnant Pass) and Mynydd y Dre ...

Volcanic Plug
A volcanic plug, also called a volcanic neck or lava neck, is a volcanic object created when magma hardens within a vent on an active volcano. When present, a plug can cause an extreme build-up of high gas pressure if rising volatile-charged magma is trapped beneath it, and this can sometimes lead to an explosive eruption. In a plinian eruption the plug is destroyed and ash is ejected. Glacial erosion can lead to exposure of the plug on one side, while a long slope of material remains on the opposite side. Such landforms are called crag and tail. If a plug is preserved, erosion may remove the surrounding rock while the erosion-resistant plug remains, producing a distinctive upstanding landform. Examples of volcanic plugs Africa Near the village of Rhumsiki in the Far North Province of Cameroon, Kapsiki Peak is an example of a volcanic plug and is one of the most photographed parts of the Mandara Mountains. Spectacular volcanic plugs are present in the center of La Gomer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
England
England is a country that is part of the United Kingdom. It shares land borders with Wales to its west and Scotland to its north. The Irish Sea lies northwest and the Celtic Sea to the southwest. It is separated from continental Europe by the North Sea to the east and the English Channel to the south. The country covers five-eighths of the island of Great Britain, which lies in the North Atlantic, and includes over 100 smaller islands, such as the Isles of Scilly and the Isle of Wight. The area now called England was first inhabited by modern humans during the Upper Paleolithic period, but takes its name from the Angles, a Germanic tribe deriving its name from the Anglia peninsula, who settled during the 5th and 6th centuries. England became a unified state in the 10th century and has had a significant cultural and legal impact on the wider world since the Age of Discovery, which began during the 15th century.

English Lake District
The Lake District, also known as the Lakes or Lakeland, is a mountainous region in North West England. A popular holiday destination, it is famous for its lakes, forests, and mountains (or ''fells''), and its associations with William Wordsworth and other Lake Poets and also with Beatrix Potter and John Ruskin. The Lake District National Park was established in 1951 and covers an area of . It was designated a UNESCO World Heritage Site in 2017. The Lake District is today completely within Cumbria, a county and administrative unit created in 1974 by the Local Government Act 1972. However, it was historically divided between three English counties ( Cumberland, Westmorland and Lancashire), sometimes referred to as the Lakes Counties. The three counties met at the Three Shire Stone on Wrynose Pass in the southern fells west of Ambleside. All the land in England higher than above sea level lies within the National Park, including Scafell Pike, the highest mountain in England. ...

British Isles
The British Isles are a group of islands in the North Atlantic Ocean off the north-western coast of continental Europe, consisting of the islands of Great Britain, Ireland, the Isle of Man, the Inner and Outer Hebrides, the Northern Isles, and over six thousand smaller islands."British Isles", ''Encyclopædia Britannica''. They have a total area of and a combined population of almost 72 million, and include two sovereign states, the Republic of Ireland (which covers roughly five-sixths of Ireland), and the United Kingdom of Great Britain and Northern Ireland. The Channel Islands, off the north coast of France, are normally taken to be part of the British Isles, even though they do not form part of the archipelago. The oldest rocks are 2.7 billion years old and are found in Ireland, Wales and the northwest of Scotland. During the Silurian period, the north-western regions collided with the south-east, which had been part of a separate continental landmass. The ...
